Gardner Bender CP2000 - 2000 lb Cable Puller - Manual (Page 7)

accumulate behind or around your legs. If you loose control of
the pull, the rope can be pulled back violently toward
the capstan.
WARNING: The rope on the capstan can crush your
hand during operation. Do not allow the rope to wrap
around any part of your body. Keep loose clothing,
hands and body away from moving parts.
During normal pulling operations, the cable resistance will
constantly change. This will require the operator to change
his tailing force in response. The operator can relax this force
completely and stop the pull at any time. The capstan
requires some tailing force before it will pull. This assures
complete operator control. Do not continue to hold the rope
on the capstan if it starts to slip. Rope wear from friction and
heat will result. This could cause the rope to break. Turn off the
motor and secure the rope.
CAUTION: This unit contains a pin designed to
shear if maximum recommended load is exceeded. This
sudden shearing action may send a shock to the rope
possibly causing injury. Avoid such hazards by wearing
leather gloves and never wrap the rope around yourself.
The CP2000 is equipped with a shear pin that will shear at
2500 lbs (1134kg) pulling force. This is for added protection
for the operator and equipment. Do not attempt a pulling
operation that exceeds this limit. If this should occur, secure
the rope and repair the unit. See Section 9.0 Repair and
Maintenance section in this manual.
On a vertical pull, resistance to the force of gravity will tend to
reverse the pull. The weight of the cable will increase as the
vertical height of the pull increases due to the added cable
length. If your equipment fails during a vertical pull the entire
cable and rope can fall. Resistance created by friction will
require more pulling force, but will not reverse the pull.
Always securely tie the rope when the pull is complete.
DANGER: Never stand directly under a vertical pull.
9.0 REPAIR AND MAINTENANCE
9.1 Shear Pin Placement
1. Remove the power drive from the CP2000 arm:
• Unthread the side handle from the power drive.
• Rotate the power drive up and slide it off from the
drive coupler.
2. Remove the drive coupler from the puller arm.
3. Remove the two (2) setscrews from the drive coupler.
4. Insert a small size punch into the setscrew hole and push
the shear pin completely out. Be careful. Do not damage
the internal threads.
NOTE: Use a wheel puller to remove the drive coupler from
the shaft, if it needs replacement. Use only mild steel .25 dia.
2
1 ⁄ 2 " long as shear pin replacement. Use the punch to install a
new shear pin and reassemble the unit.
9.2 Lubrication
Monthly:
• Apply EP 80/90 gear lube to the arm pivot thru the hole in
the shaft.
• Apply EP 80/90 gear lube to the puller sheave thru the hole
in the sheave.
• Apply high temperature bearing grease to the grease fitting
in the end of the capstan.
• Use a dry silicone spray as needed to lubricate the arm
extension and leg extension. This will also protect
against rust.
NOTE: Lubricate the power drive as per specifications of
drive manufacturer.
